Today is the offical day to remember and recognize Martin Luther King Jr., known as the greatest civil rights leaders in history.

In addition to his accomplishments, Dr. King is also an important lesson for leaders. He exemplified the servant leader who led without any official power. He communicated a vision of how things could be different in his “I Have a Dream” speech and he made a remarkable difference.

Take a few minutes and watch the video clip of one of the world's greatest speeches.
